Instead of blaming an airline accident on pilot error, investigators should find out why the error was made by analyzing airplane design, airline management, and pilot-training programs. For only then can changes be made to ensure that the same type of error does not recur and cause another accident.
Which of the following is a presupposition of the argument above?

(A) Pilot error is not a contributing factor in most airline accidents.
(B) Airline companies themselves should be the agents who investigate airline accidents.
(C) Stricter government regulation of airline companies will make air travel significantly safer.
(D) Investigators of airline accidents should contribute to the prevention of future accidents.
(E) Most pilots who make errors in flying will repeat their errors unless they are retrained.
为什么答案是D,而不是A呢？

"in most airline accidents" - Never mentioned in the passage.

(A) Pilot error is not a contributing factor in most airline accidents.

但是"in most airline accidents" 正是加强了A的取非反对原文，if"Pilot error is  a contributing factor in most airline accidents"则原文被极大反对。

除非是我对此题的理解出现偏差，将其重点和非重点搞混了

本文意思并没有否定飞行员没责任, 而是除了飞行员的责任外还有其他的因素, 须综合调查.
